The Tarantula Nebula, also known as 30 Doradus, is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud. About 160 thousand light-years away, it’s the largest, most violent star forming region known in the whole Local Group of galaxies. The cosmic arachnid is near […]

Was this a lucky shot? Although many amazing photographs are taken by someone who just happened to be in the right place at the right time, this image took skill and careful planning. First was the angular scale: if you shoot too close to the famous Arc de Triomphe in Paris, France, the full moon will appear […]

Did you see an aurora over the past two nights? Many people who don’t live in Earth’s far north did. Reports of aurora came in not only from northern locales in the USA as Alaska, but as far south as Texas and Arizona. A huge auroral oval extended over Europe and Asia, too. Pictured, an […]

What powers this unusual nebula? CTB-1 is the expanding gas shell that was left when a massive star toward the constellation of Cassiopeia exploded about 10,000 years ago. The star likely detonated when it ran out of elements near its core that could create stabilizing pressure with nuclear fusion. The resulting supernova remnant, nicknamed the […]

What’s happening over the water? Pictured here is one of the better images yet recorded of a waterspout, a type of tornado that occurs over water. Waterspouts are spinning columns of rising moist air that typically form over warm water. Waterspouts can be as dangerous as tornadoes and can feature wind speeds over 200 kilometers […]

In visible light NGC 1333 is seen as a reflection nebula, dominated by bluish hues characteristic of starlight reflected by interstellar dust. A mere 1,000 light-years distant toward the heroic constellation Perseus, it lies at the edge of a large, star-forming molecular cloud. This Hubble Space Telescope close-up frames a region just over 1 light-year […]

Along a narrow path that mostly avoided landfall, the shadow of the New Moon raced across planet Earth’s southern hemisphere on April 20 to create a rare annular-total or hybrid solar eclipse. A mere 62 seconds of totality could be seen though, when the dark central lunar shadow just grazed the North West Cape, a […]
